Philosophy of care | I believe every patient should be treated as if they were your family. Medicine can be complex, and I will explain it to you in such a way as to convey your health problem in a straightforward manner, with compassion and empathy. | Why I entered medicine | My grandfather, who raised me, was an anesthesiologist. His stories of the operating room would always fascinate me, and began my interest in medicine. Once when I was injured as a child and brought to the hospital, I felt my care could have been better in many ways. It is from that perspective that I approach each patient and their family – always striving to be better. | Community involvement | For many years I have supported the Children's Home of Easton, who house, feed, and educate children at risk.

"Philosophy of care | As a medical oncologist, I try to empower my patients as much as possible – I will give you information, make recommendations, and encourage you to make informed decisions. Many of my patients initially (with newly-diagnosed cancer) have significant internal chaos. Providing information and orientation is often very calming – it is like shining a flashlight in a dark cave, so that one can see what is there, and understand everything better. When I meet you for the first time, sometimes the most important thing that I can do is to restore order to that internal chaos. | Why I entered medicine | I grew up with significant allergies, asthma and eczema during a time when there were no bronchodilators, and allergies were poorly understood. Due to sparse knowledge, I was constantly exposed to allergens from dogs, cats, feather pillows, etc. Due to sparse medical remedies (only prednisone available at that time), I was seemingly always ill. This engendered a desire to become a doctor and somehow exert some control. I was also interested in working in a field that would enable me to serve people in need. Medical oncology interested me in particular, because its research questions closely aligned with my research interests in graduate school. | Community involvement | In the past, I was a volunteer for WOAR (Women Organized Against Rape) in Philadelphia, and acted as a rape crisis counselor at one of the designated intake ERs in the city. I also participated in developing a Safe Touch program in the Philadelphia school system. As a WOAR volunteer, I conducted workshops with parents and teachers about teaching Safe Touch to children, in order to help children recognize sexual abuse and feel empowered to report it. | Personal interests | My favorite thing in the whole world now is to spend time with my (grown) children and other family members. In a ""previous life"", I used to enjoy tent camping, ballroom dancing, playing the piano, crocheting, and reading (Sci Fi books).".
